Nondiagnostic 99m Tc-MAG3 Diuresis Renography Studies Caused by Propofol Sedation : A Case Series.

99m Tc-MAG3 diuresis renography is a noninvasive functional imaging technique used to assess clearance of radiotracer in a dilated urinary tract under high diuresis. It is commonly performed in patients to diagnose functionally significant urinary tract obstruction. In some pediatric patients, sedation is required to enable imaging.
